It is to be observed that the Sill, end sides of the frame, are each made from a onepiece sheet of metal bent on'peruliel lines only, and that the top member of the frame is Similarly made, except that for conventhereoiC is made to slide into locking engagement with the two face Walls of that memberu The sill member A has at its lower outer angle e. doubled iielige ,is provided et AJ", justoelow the inner sash with groove over which e 'lip of the sash projects, and rises :it As just within the sash. port-ion the web descends vertically to meet rigei i 1 i From this raised over .bolts E, l.

the plate being i this 1l) -window frame having in its side members 'provide' gle sheet by near the jam-b, as usual, while the other fold of the chain, carrying the counterbalancing weight, hangs at some distance from the opposite face of the jamb. Obviously, the Weight of the sash and counterbalance is thus borne by the jamb and there is no strain upon the plate retaining screws. The bead or strip B and the screws C being removed, the pulley plate may be conveniently removed, with its pulleys, and replaced without disturbing other parts .the inner end of swung ldownward while the outer end is raised and the plate being then moved longitudinally inward and downward. To facilitate engagin the plate for this pur ose, apertures C20 t erein may be The bead or strip B and the stop B2, owing to their being confined in the recesses cannot spread when heated, and the'stop, being more exposed, is provided with a dou- B12 and with a web B13 to prevent from'moving toward the opposite wall o the recess when heated.

It is to be noted that the jamb has its outer s topintegral, and that both the remaining stops ie partl between the sash and jamb so that the sasv protects them and -aids in holding them in place; that the sali; ent portions of the jambs enter openings in the sill and head; that the upper sash hel to rotect and hold the pulley plate, whi e its ip enteringV a recess in the head jamb excludes air and the sash from bending when heated; that the pocket plate is held and protected by the stops and lower sash; that the lip on the lower sashrail shutting over the otlset in the sill revents inward curvature as well as excludls air; that the curved offset in the sill turns entering air outward, and that the inner offset of the sill holds the inner side of the rail.

It is especially important that each ot' the main frame members is formed from a sinsuccessive bending on parallel lmes, being first cut to exact form and suitabl perforated by dies.

1. The combination with a sheet metal or )ambs recesses in position to be partially overlap ed, laterally, by the lateral ed e faces o a sash in normal position in te frame, of stops each in pos1tion to engage the inside face of the corresponding sash and each having a base adapted't'o extend between the edge face of the sash and the bottom of the corresponding recess.

2. The combinationv with a sheet metal Window frame having its side or jamb memprevents the central part of l-means for detachably bers each bent to form an integral outer sash stop and a recess in position to be partially overlapped and covered by the lateral edge face ot the sash, of a stop adapted to engage the inside face of the saslvand having a broad base portion in position to extend between said edge face and the bottom ofthe corresponding recess.

3. The combination with a sheet metall window frame having its side body memintegral, laterally grooved sash stops and cut away to 'form openings to the pockets, of `plates, for closing said openings, having one lateral margin 'entering the ybody members and in hooked engagement with one of said vstops and its other lateral margin overlapped upon the bod member in position to be held by an insi e removable stop.

4. The' combination with a sheet metall Window frame having hollow side members cut away. to form a'n openin extending across both sash spaces, of a c osing plate for said openin bent into conformity with the jamb Wall a ove and below the opening.

5.' A `sheet metal window sill having its inclined upper wall bent upwardly and forwardly upon itself and then sharply rearward parallele to its original direction, to formfbelow the' place of the lower sash' and just within the plane of its outer face an upward offset having an outer face adapted to reverse the current of incomin fluid and direct -it against the usual sash' 11p rprojecting over the offset against the body of the sill.` I 6. TheA combination with a sheet vmetal window frame having in its side jamb faces which are adjacent to the edges of the sash longitudinal recesses adapted to be covered in part by the edge faces of the sash, of stops having broad vbases lling said recesses 'from side to side, respectively, and provided with l narrower longitudinal salient portions adapted to overlap the broader face of the sash, substantially as set forth.

. 7 lThe combination with a sheet metal window frame having stop-receiving grooves`of sheet' metal stops having laterall projecting bases which are flush with the ]ambs and themselves have lateral lmarginal, flanges projecting to the bottoms of the grooves, and securing the stops 1n their grooves.

In testimon whereof I affix my signature in presence o two Witnesses.
